ESPAR(Electronically Steerable Parasitic Array Radiator) 안테나는 기존의 다중 안테나 시스템이 가지는 다중 RF-체인으로 인한 공간적인 제한과 에너지 효율의 문제를 극복하는 기술이다. 다중 안테나와 다중 RF-체인을 사용함으로써 발생하는 문제를 해결하기 위해 단일 RF 체인을 갖는 ESPAR 안테나를 사용하여 다수의 데이터를 동시에 전송할 수 있는 빔 공간 MIMO 시스템이 제안되었다. 기존 연구에서는 PSK 변조 계열에서의 빔 공간 MIMO 시스템에 대해 제안되었다. 본 논문에서는 1개의 능동소자와 2개의 기생소자를 가지는 ESPAR 안테나를 사용하여 PSK 변조뿐만 아니라 QAM 변조에서도 빔 공간 MIMO 시스템이 가능하다는 것을 밝히기 위해 16, 64-QAM 변조방식을 이용한 2x2 빔 공간 MIMO 시스템을 제안하고 성능을 평가하였다. ESPAR 안테나의 기생 소자의 리액턴스를 조절하여 리액턴스 셋을 생성하여 QAM 계열의 심볼을 생성할 수 있다는 것을 확인하고 시뮬레이션을 통해 이를 전송하여 빔 공간 MIMO 시스템의 통신성능이 기존의 MIMO 시스템과 유사하게 되는 것을 확인하였다.

시대정신을 함유하고 사회와 역사를 통해 인간을 고찰하며 삶과 현 세대를 자각케 하는 예술적 완성도가 높은 영화의 구성과 상징표현 그리고 스타일 등을 분석하여 그 내적 의미와 철학의 표현을 분석하는 것은 대중예술로서 영화에 있어 매우 뜻 깊으며 가치 있는 연구 일 것이다. 영화 로마는 절제하고 감추고 생략함으로써 대중들의 마음 속 빈틈을 파고들고 절제되었으며, 흑백영화로써 색감도 감췄다. 인종, 자본, 사회적으로 억압된 역사와 가정부로 살아가는 일상의 아이러니한 메시지를 표현하는 상징적 이미지를 통한 미학적 시도를 많이 발견할 수 있다. 많은 대조를 통한 상징적 표현과 사물을 통한 상징적 표현을 영화 속에 그려내며 자신만의 작가주의적인 영상언어를 구사하고 있음을 알 수 있다. 이러한 예술적 가치를 함유한 상업 영화의 분석은 예술영화의 나아갈 바에 대한 척도와 작가주의적 표현기법의 선례로 향후 작품 제작에 있어 도움을 줄 것으로 기대된다.

본 논문은 HEVC의 엔트로피 코딩방법인 CABAC Encoder를 위한 효율적인 하드웨어 구조를 제안한다. CABAC의 이진 산술 부호화(Binary Arithmetic Encode)는 각 단계간의 의존도가 높아 빠른 연산이 어렵다. 제안하는 이진 산술 부호화기는 입력으로 들어오는 빈을 고속으로 처리하기 위하여 4단계의 파이프라인 구조로 설계 되었다. 입력 빈의 값에 따라 MPS(Most Probable Symbol) 혹은 LPS(Least Probable Symbol)로 결정되어 이진 산술 부호화를 수행 하며 반복되는 연산으로 발생하는 Critical path는 LUT를 사용하여 줄일 수 있었고 하드웨어 면적을 줄이기 위해 메모리를 사용하지 않는 구조로 설계 되었다. 제안하는 CABAC의 이진 산술 부호화기는 Verilog-HDL로 설계하였으며 65nm 공정으로 합성하였다. 합성 결과 게이트수는 3.17k 이며 최대 동작주파수는 1.53GHz이다.

The objective of this project is to improve the environment of the estuary dike on the Youngsan-River through Re-landscaping. An estuary dike of the Youngsan-River, the largest in the Orient, was constructed in 1981 and connects Mokpo City and Youngam-Gun province. Twenty years ago, when this dike was completed, this place was one of the famous tourist attractions of Korea. It symbolized the development and growth of Korea. But this dike at present is only a dreary sight as a huge concrete construction element. Therefore, a wall painting on the estuary dike was planned to improve this image. The site, an estuary dike of the Youngsan-River, is located in Mokpo City and its length is about 1,360m. The planning focus of this re-landscaping, which is a proposed improvement design through the analysis of characteristics and problems in conventional facilities, is as follows: (1) Introduction of a wall painting that is a symbol of the sea and river (by the creation of an illusion), (2) Production of the wall painting which is under consideration to create a friendly atmosphere of the circumference view and (3) Preparation of a design to establish an approach to the waterfront. By following these steps, an estuary dike can function as a tourist attractions and can be transformed in to cultural space for civilian. This project is good example of environment design that is completed with the regional residents participation through community input in the planning and initiation of a wall painting. The concept of environment design which involves the residents participation and re-landscaping in Korea has not been established up to now on. However, as this projects has proven, consideration for regional residents is a very important factor for the administrative office and planing specialist to address. In the future, it will have a direct influence on the development of design planning. If the establishment of space that can be accepted by residents with love, affection and self-confidence is possible, environment design in which residents participate actively, can be realized.

Recently, the interior design of electric home appliance stores requires comprehensive image management with systemic marketing strategies and consistence in order to attract consumers to purchase products. However, the environment of domestic electric home appliance stores is complex and confused by indiscreet design factors and operation. Despite of the fact that company costs a lot of money to manage each store, consumers are not provided with selling environment with high quality. On the other hand, it is inevitable to compete with foreign specialized stores and discount malls due to opening distribution market. Besides, company has faced to attract customers with distinct strategies in order to survive in various competition system. In this sense, in store environment, there should be consistent image in interior design of the store based on management ideology of the company for the successful management of electric home appliance stores. The purpose of this research is to investigate and analyze the case of Samsung Electronics's electric home appliance stores among domestic electric home appliance stores that is applied with Store Identity Program (hereafter SIP) and to suggest solutions for the problems. Therefore, it is purposed to use as references for the stores that has the similar interior design plan. The result of this study is to upgrade the store image through providing basic data about role of data and distinct factors for competitive design as a part of Store Identity Strategy. Furthermore, it can be important data to optimize the profits and to make positive space for both consumer and company as company and products are credible with mental satisfaction of consumers if there is enough study on SIP and process and symbol of company and products to consumers, enough recognition and improvement on problems.

This paper aims to study on the periodical competition, the program, the jury organization, the reward, and copyright applied to the buildings which were constructed with architectural design competition performed in European and American region between 19c and 20c. The results of this study are as follows; 1. Befor 1900 Period, the type of buildings added to the competition program; between 1900 period and 1950 period, the works of strong nationality and rich local color were preferred; After 1950 period, the design drawings of high symbol and function were chosen 2. There are three types of design competitions: the open design competition, the invited and limited design competition, and the idea design competition. The open design competition has been most often made. 3. The juries were, most of all, composed of professional architects over 30 percent. 4. The program was written about building scale and appointments, described what form drawings, brief notes and air perspective wood have to be submitted. For instance, the use of colour was not permitted in the drawings, as this might possibly mislead the jurors. 5. The reward was given to the winners; the copyright was given to the first prize winner. 6. The standard of entry's qualification was mostly architect 7, Entry term was from a minimum month to a maximum year after annoncement of competition, it was approximetly 63% between 4 months and 8 months. I am convinced that architect gets freedom of pure creation and joy of society service through competition, architect justifies his profession and keep his useful and creative effort to society constantly, as long as the competition exists.

This study was done for the proposal for improvement for junior sportswear which is substitutable as uniforms in the form of elementary school and physical education uniforms by analyzing detailed features through investigation. Accordingly, we developed a prototype design for physical education uniforms as a symbol of the school to enhance the aesthetic and functional satisfaction. The results are as follows. When we developed physical education uniforms, we put activity on our first priority while taking the improvement in both aesthetic and functional aspects into consideration. In addition, we tried to make sure the uniforms reflect the refined and trendy elements to meet students needs to satisfy their aesthetic sense in dress. Reflecting the improvement proposals and preferences of the students, six different prototype designs were developed and evaluated on the basis of two concepts of "new basic" and "trendy". The highest ranking, the physical education uniforms design 1 is based on new basic concept and characterized with slim fit considering activity which will be worn as fall/winter physical education uniforms. Design 1 uses ottoman functional knit as a fabric material which is not only students favorite but also good in both flexibility and warmth. Top with style of high-neckline collar and full open zip-up is simplified with the incision lines and detail. It is a set-in sleeve design in which blue and yellow collars signifying school color are properly placed along with the incision lines in harmony.
